Description

Channel transmission method, terminal equipment and network equipment

The application is a divisional application of an invention patent application with the application number of 201880037043.3, which is filed on 12.1.2018 and is named as a transmission channel method, a terminal device and a network device.

Technical Field

The present application relates to the field of communications, and in particular, to a method for transmitting a channel, a terminal device, and a network device.

Background

In the LTE system, the time domain position of a data channel (e.g., a Physical Downlink Shared Channel (PDSCH)) is in units of time slots and subframes. For example, the starting position of the PDSCH is relative to the slot/subframe in which it is located, and the PDSCH is indicated in the Physical Control Format Indicator Channel (PCFICH) of the subframe to start from the first time domain symbol of the subframe.

However, in the New Radio (NR) system of the fifth generation (5th generation, 5G), in order to improve the flexibility of resource allocation and reduce the delay, the flexibility of the time domain position of the channel is greatly improved, and the channel is allocated in units of symbols, so that it is necessary to indicate the starting symbol position of the channel.

Currently, regarding the way of indicating the starting symbol position of the channel, two technical solutions are proposed in the 5G research: one is to indicate the starting symbol position of the channel based on the starting position of the slot, but the scheduled channel is always located after the downlink control channel that schedules the channel, and since it is not known in advance which position of the slot the downlink control channel is located, the possible starting symbol positions can only be generally distributed in the slot as uniformly as possible. When the downlink control channel is located at some position, the scheduled channel generally selects the nearest time domain position behind the scheduled channel, and the position is probably unable to be close to the downlink control channel, so that low-delay scheduling cannot be realized.

The second scheme is to indicate the starting symbol position of the channel based on the position of the downlink control channel. When the downlink control channel is located at any position, the starting symbol of the scheduled channel can be configured at the position next to the downlink control channel. However, this scheme cannot effectively schedule a channel far away from the downlink control channel, and if the distance between the start symbol of the scheduled channel and the downlink control channel exceeds 1 timeslot, the control overhead of the scheme will increase sharply.

Disclosure of Invention

The application provides a channel transmission method, terminal equipment and network equipment, which can make full use of limited control signaling overhead and effectively indicate the starting symbol position of a scheduled channel.

In a first aspect, a method for transmitting a channel is provided, the method including: receiving a resource configuration message sent by a network device, where the resource configuration message includes at least one time domain symbol position information, where different time domain symbol position information in the at least one time domain symbol position information is used to indicate different positions of a starting time domain symbol occupied by a channel to be scheduled, where the type of any one of the at least one time domain symbol position information is a first type or a second type, the first type of time domain symbol position information is used to indicate a relative position between the starting time domain symbol occupied by the channel to be scheduled and a time slot in which the channel to be scheduled is located, and the second type of time domain symbol position information is used to indicate a relative position between the starting time domain symbol occupied by the channel to be scheduled and a time domain resource in which target control information is located; determining the type of target time domain symbol position information in the at least one time domain symbol position information; determining the position of the initial time domain symbol occupied by the channel to be scheduled, which is indicated by the target time domain symbol position information, as a target position according to the type of the target time domain symbol position information; and transmitting the channel to be scheduled with the network equipment according to the target position.

Fig. 1 shows a schematic flow diagram of a method 100 of transmitting a channel according to an embodiment of the application, which method 100 may be performed by a terminal device. As shown in fig. 1, the method 100 includes: s110, receiving a resource configuration message sent by a network device, where the resource configuration message includes at least one time domain symbol position information, where different time domain symbol position information in the at least one time domain symbol position information is used to indicate different positions of a starting time domain symbol of a channel to be scheduled, a type of any one time domain symbol position information in the at least one time domain symbol position information is a first type or a second type, the first type of time domain symbol position information is used to indicate a relative position between the starting time domain symbol occupied by the channel to be scheduled and a time slot where the channel to be scheduled is located, and the second type of time domain symbol position information is used to indicate a relative position between the starting time domain symbol occupied by the channel to be scheduled and a time domain resource where target control information is located; s120, determining the type of the target time domain symbol position information in the at least one time domain symbol position information; s130, determining the position of the initial time domain symbol occupied by the channel to be scheduled, which is indicated by the target time domain symbol position information, as a target position according to the type of the target time domain symbol position information; s140, transmitting the channel to be scheduled with the network device according to the target location.

In an embodiment, a channel to be scheduled in the embodiment of the present application may be any one of a PUCCH, a PDCCH, a PUSCH, and a PDSCH.

Specifically, in S110, the terminal device receives a resource configuration message sent by the network device, where the resource configuration message includes at least one time domain symbol location information, for example, the resource configuration message may be RRC signaling or system information, that is, the terminal device receives RRC signaling or system information sent by the network device, where the RRC signaling or system information includes the at least one time domain symbol location information. The time domain symbol position information of the at least one time domain symbol position information is used for indicating different time domain positions, the different time domain positions represent possible positions of a starting time domain symbol occupied by a channel to be scheduled, the type of any time domain symbol position information in the at least one time domain symbol position information is a first type or a second type, and the time domain symbol position information of different types indicates the starting time domain symbol position occupied by the channel to be scheduled in different modes.

Specifically, the first type of time domain symbol position information is used to indicate a relative position between a starting time domain symbol occupied by a channel to be scheduled and a time slot in which the channel to be scheduled is located; and the second type of time domain symbol position information is used for indicating the relative position between the starting time domain symbol occupied by the channel to be scheduled and the time domain resource where the target control information is located.

It should be understood that the target control information in this embodiment may be Downlink Control Information (DCI) used for scheduling the channel to be scheduled, and this embodiment is not limited thereto.

In an embodiment of the present application, the method 100 further includes: the terminal device determines target time domain symbol position information in the at least one time domain symbol position information, and in S120, the terminal device determines the type of the target time domain symbol position information, that is, determines that the target time domain symbol position information is of the first type or the second type.

It should be understood that the terminal device determining the target time domain symbol position information in the at least one time domain symbol position information may include: and the terminal equipment receives target control information sent by the network equipment, wherein the target control information is used for indicating the target time domain symbol position information, so that the terminal equipment can determine the target time domain symbol position information according to the target control information. Specifically, the target control information may include an identifier of the target time domain symbol position information, for example, a number of the target time domain symbol position information. Each time domain symbol position information in at least one time domain symbol position information received by the terminal equipment has a respective number, and the terminal equipment determines corresponding target time domain symbol position information according to the number included in the target control information.

In this embodiment of the present application, the determining, by the terminal device, the type of the target time domain symbol position information may include: the terminal device receives target control information sent by the network device, wherein the target control information is used for indicating target time domain symbol position information and the type of the target time domain symbol position information.

In an embodiment, the determining, by the terminal device, the type of the target time domain symbol position information may further include: the target time domain symbol position information comprises a type parameter, and the terminal equipment determines the type of the target time domain symbol position information according to the type parameter. For example, each time domain symbol position information in at least one time domain symbol position information received by the terminal device includes a type parameter, and the type parameter is used to indicate a type of the corresponding time domain symbol position information, that is, the type parameter included in the target time domain symbol position information is used to indicate the type of the target time domain symbol position information.

In an embodiment, the determining, by the terminal device, the type of the target time domain symbol position information may further include: and determining the type of the target time domain symbol position information according to a preset rule. Specifically, the terminal device receives a resource configuration message sent by the network device, where the resource configuration message includes at least one time domain symbol position information and also includes at least one slot level offset parameter corresponding to the at least one time domain symbol position information, and each slot level offset parameter is used to indicate a type of the corresponding time domain symbol position information, for example, a target slot level offset parameter corresponding to the target time domain symbol position information is used to indicate a type of the target time domain symbol position information.

Specifically, the terminal device determines the type of the target time domain symbol position information according to a preset rule, where the preset rule may be: and the terminal equipment determines the type of the target time domain symbol position information according to the target time slot level offset parameter. Specifically, if the target slot level offset parameter is not equal to 0, the type of the target time domain symbol position information is a first type, and if the target slot level offset parameter is equal to 0, the type of the target time domain symbol position information is a second type, but the embodiment of the present application is not limited thereto.

In this embodiment of the present application, a position indicated by the target time domain symbol position information is determined according to the type of the target time domain symbol position information. Specifically, the target time domain symbol position information may be any one of the at least one time domain symbol position information, the target time domain symbol position information includes a relative position parameter, the type of the target time domain symbol position information may be a first type or a second type, and correspondingly, the relative position parameter in the target time domain symbol position information also represents different meanings.

As an embodiment, if the target time domain symbol position information is a first type of time domain symbol position information, that is, the target time domain symbol position information is used to indicate a relative position between a starting time domain symbol occupied by a channel to be scheduled and a time slot in which the channel to be scheduled is located, a relative position parameter in the target time domain symbol position information may represent a relative position between the starting time domain symbol occupied by the channel to be scheduled and the starting time domain symbol of the time slot in which the channel to be scheduled is located.

Specifically, taking fig. 2 as an example, for a slot, the slot includes 14 time domain symbols, which may be Orthogonal Frequency Division Multiplexing (OFDM) symbols, and since it is not known in advance where the downlink control channel is located in the slot, the possible starting symbol positions are generally distributed as uniformly as possible in the slot. For example, at the four positions of the cross-line frame in fig. 2, which are 0 th, 4 th, 8 th and 12 th time domain symbols respectively, the relative positions of the 4 positions and the starting time domain symbol position of the timeslot are 0, 4 th, 8 th and 12 th, respectively, then the 4 positions can be respectively indicated as the positions of the starting time domain symbols occupied by the channel to be scheduled through the 4 first types of time domain symbol position information. For example, if the target time domain symbol position information is of the first type, and the position of the start time domain symbol occupied by the channel to be scheduled is represented by the target time domain symbol position information as time domain symbol 4 in fig. 2, the relative position parameter in the target time domain symbol position information represents the relative position of the start time domain symbol occupied by the channel to be scheduled and the start time domain symbol of the time slot, that is, 4 time domain symbols.

For the time domain symbol position information of the first type, since the position of the downlink control channel (e.g. PDCCH) is not known in advance, if the PDCCH is located at the position of the time domain symbol 5 as shown in fig. 2, the starting symbol position occupied by the channel to be scheduled is generally selected to be the position closest to the PDCCH, i.e. the time domain symbol 8. However, such a selection still causes a gap between the two time domain symbols, which may result in that the channel to be scheduled cannot be transmitted in close proximity to the PDCCH, and thus, scheduling with low delay cannot be achieved.

As an embodiment, if the target time domain symbol position information is the second type of time domain symbol position information, that is, the target time domain symbol position information is used to indicate the relative position between the starting time domain symbol occupied by the channel to be scheduled and the time domain resource where the target control information is located, the relative position parameter in the target time domain symbol position information may represent the relative position between the starting time domain symbol occupied by the channel to be scheduled and the time domain resource where the target control information is located. In an embodiment, the relative position parameter in the target time domain symbol position information may also represent a relative position between a starting time domain symbol occupied by the channel to be scheduled and a starting time domain symbol or an end time domain symbol of a control resource set or a search space in which the target control information is located.

Specifically, taking fig. 3 as an example, the same time slot includes 14 time domain symbols, where the time domain symbols may be OFDM symbols, and for a downlink control channel carrying target control information, for example, a PDCCH may be located at any position, after the PDCCH is located, a starting symbol of a channel to be scheduled may be configured at any position after the position of the PDCCH, for example, the PDCCH in fig. 3 is located at time domain symbol 4,

time domain symbols

5, 6, 7, and 12 after the PDCCH may be set as possible positions of the starting time domain symbol of the channel to be scheduled, and relative positions between the 4 positions and the time domain symbol occupied by the PDCCH are respectively 1, 2, 3, and 7, and then the 4 positions may be respectively indicated as positions of the starting time domain symbol occupied by the channel to be scheduled through 4 pieces of second-type time domain symbol position information. For example, if the target time domain symbol position information is of the second type and the position of the start time domain symbol occupied by the channel to be scheduled is represented by the target time domain symbol position information as the time domain symbol 6 in fig. 3, the relative position parameter in the target time domain symbol position information represents the relative position of the start time domain symbol occupied by the channel to be scheduled and the start time domain symbol occupied by the target control information (i.e., PDCCH), that is, 2 time domain symbols.

It should be understood that, when the target time domain symbol position information is of the second type, the relative position parameter in the target time domain symbol position information may also represent a relative position between a starting time domain symbol occupied by the channel to be scheduled and a control resource set or a search space where the target control information is located, for example, a starting or ending position of the control resource set or the search space may be used as a reference.

In an embodiment, taking fig. 4 as an example, if a starting time domain symbol occupied by a channel to be scheduled is shown by a cross-line frame in fig. 4, and a time domain resource occupied by a control resource set where target control information is located or a search space is shown by a dashed-line frame in fig. 4, correspondingly, as shown in fig. 4, a relative position parameter in the target time domain symbol position information may represent a relative position between the starting time domain symbol occupied by the channel to be scheduled and the starting time domain symbol of the control resource set where the target control information is located or the starting time domain symbol of the search space.

In an embodiment, taking fig. 5 as an example, if a starting time domain symbol occupied by a channel to be scheduled is shown by a cross-line frame in fig. 5, and a time domain resource occupied by a control resource set where target control information is located or a search space is shown by a dashed-line frame in fig. 5, correspondingly, as shown in fig. 5, a relative position parameter in target time domain symbol position information may represent a relative position between the starting time domain symbol occupied by the channel to be scheduled and a control resource set where the target control information is located or an end time domain symbol of the search space

However, the second type is adopted for the target time domain symbol position information, and since a channel far away from the PDCCH cannot be effectively scheduled, if the distance between the starting symbol of the channel to be scheduled and the PDCCH exceeds 1 time slot, the overhead of the second type of time domain symbol position information is sharply increased by the indication in this way, and therefore, the second type is usually adopted when the distance between the channel to be scheduled and the PDCCH is relatively close.

It should be understood that, in the embodiment of the present application, each time domain symbol position information in the at least one time domain symbol position information may further include a length parameter, for example, the target time domain symbol position information includes a length parameter, and the length parameter may represent a length of a time domain resource occupied by a channel to be scheduled, for example, the number of time domain symbols occupied by the channel to be scheduled, but the embodiment of the present application is not limited thereto.

It should be understood that, in this embodiment of the present application, the time domain resource occupied by the channel to be scheduled may be continuous, that is, may be one or more connected time domain symbols, or the time domain resource occupied by the channel to be scheduled may also be discontinuous, for example, a position of each time domain symbol in the time domain resource occupied by the channel to be scheduled may be determined through a correlation algorithm, and this embodiment of the present application is not limited thereto.

In S130, the terminal device determines, according to the type of the target time domain symbol position information, that the target time domain symbol position information indication position is a target position, where the target position is a position of an initial time domain symbol occupied by the channel to be scheduled; and in S140, the terminal device transmits the channel to be scheduled with the network device according to the target location.

Therefore, in the method for transmitting a channel in this embodiment of the present application, a terminal device receives at least one time domain symbol position information sent by a network device, where different time domain symbol position information is used to indicate different positions of a time domain symbol occupied by a channel to be scheduled, the terminal device determines target time domain symbol position information in the at least one time domain symbol position information and a type of the target time domain symbol position information, and further determines a position indicated by the target time domain symbol position information, and transmits the channel to be scheduled through the position, because the types of the target time domain symbol position information are different, and a manner of indicating a time domain symbol position is also different, thereby implementing flexible indication of two types of time domain symbol position information, for example, when a downlink control channel is closer to the channel to be scheduled, a starting symbol position of the channel to be scheduled can be indicated by using a relative downlink control channel, and when the channel to be scheduled is far away from the downlink control channel, indicating the initial symbol position of the channel to be scheduled by adopting the initial position of the time slot corresponding to the channel to be scheduled.
